' Application filed October 10, 1921.. Serial No. 506,850.

To all whom it may concern: 7

Be It known that I, THoMAs GANDERTON,

'a citizen of the United States, and resident of Beaver, in the county of Beaver and State of Pennsylvania, have invented certain new,

and useful Improvements in Automatic Controls for Intake Passages, of which I hereb} declare the following to be a full, clear, and,

exact description, such as will enable. others skilled in the art to which it appertains, to

make and use the same.

The invention relates to means for supplying additional air to the explosive mixture of the engine of a motor car when the car is moving up an incline, in order to increase the amount of power developed by the engine proportionately to the increased demand made upon the engine to overcome the grade.

The invention includes an automatically acting air valve, by meansof which the air is supplied in proportion to the steepness of the grade, and also includes a valve operated by the action of a pendulum to close the valve more or less completely, according to the steepness of the grade, as the machine is ascending the grade, and to open the valve when the machine is moving down the grade to permit th introduction of a volume of air, determined by the steepness of the grade, the action of the pendulum being such I as to open the valve more or less and to supply air to weaken the explosive mixture, when the machine is travelling on the level, and to retain it open on a down grade, since no power will be required when moving 7 down grade.

' The inventlon further includes a horizon tal projecting air assage or tube, inserted in the intake passage of the cylinders and a sleeve valve rotatable thereon, the aforesaid sleeve valve being automatically operated by the action of a pendulum to open and close opposed air inlet ports located in said valve and tube respectively.

The invention further includes means for preventing opening of. the valve when the car is moving up hill.

The invention is hereinafter further de-- scribed, shown in the accompanying drawings, and specifically pointed out in the claim.

In the accompanying drawings, Fig. 1 is a side elevation of the intake manifold, showing the pendulum actuated valve; Fig. 2 is an enlarged view of the valve; Fig. 3 is a longitudinal section thereof; Fig. 4 is a transverse section thereof.

In these views, 1 represents the intake manifold; 2' is an air inlet tube, the inner end of which is inserted in the opening, 6, in the manifold. j

The tube, 2, is closed at the outer end," and provided with radial perforations or ports, 5 5*, for air admission. Upon the projecting portion of the air tube is positioned the valve sleeve, 4, which is provided with corresponding air admission perforations, or ports, 5, 5.

A pendulum weight, 3, is attached to the valve sleeve. In action, when the car is ascending an incline, the pendulum will restrain the valve from movement while the.

air inlet tube will rotate, thus closing the air with the air admission tube and prevents the opening of the ports when the car is ascendupon the sleeve, causes the sleeve to rotate i11 a rade and a shoulder 11" s aced therefrom, engages the pin, 12, when the ear is moving on a down grade, and prevents the sleeve from closing the ports, 5 and 5e. The pin conveniently enters a recess,

having the shoulders, 11 and 11*, upon its opposite sides.

The action of this device is altogether automatic and requires no attention. The sleeve is preferably retained in place upon the air admission tube by means of aispring, 7,

washers and pin, 8 and 9, and a shoulder, 7

10, upon theair tube.

Having described the inventionQwhat I claimas new and desire to secure by Letters Patent, is: I v r In an automatic'allyacting valve for an auxiliary air outlet, to the intake manifold of an explosion engine, the combination with a flanged carburetor outlet pipe, of a tube, the inner endof which is inserted in an opening in th manifold, said tube being closed at its outer end and provided with aligned radial ports for air admission, a valve sleeve mounted upon the projecting 'groz'tien of the air tube, said sleeve provided with corresponding Ebil admission ports, a pendulum Weight attached to said sleeve, 2L coiled'spi'ing upon the projecting extremity of said tube, retaining means therefor upon the extremity of said tube, a Washer between said tube and sleeve, a lug upon an enlarged portion of said tube, and a recess in the end of said sleeve, said lug entering said recess, and positioned to engage one side of saidrecess when said tube is rotated as the engine is tilted to ascend an incline, to pre vent the'openingof said ports, and to 'en- V gage the other side of sand recess when the engine is descending an inoline, to prevent the closing of said ports, substantially as described.

In testimony whereof, I hereunto hand this 29 day of August, 1921.
